As we saw previously,…polygons and circles create…fundamentally different geometry.…One extrudes to a smooth object,…the other extrudes to hard edges.…Let's take a look at how this works.…So I'm going to start with a circle,…and notice the circle has a number of sides,…because it essentially is just a polygon.…So I'm gonna go ahead and just drag out a circle here,…and then let's create an identical polygon.…So I'm gonna go ahead and create a polygon,…and I'm gonna type in 24 for the number of sides.…

Let's just go ahead and drag that out.…Now when we take a look at these,…they look pretty much identical.…But they're different when we extrude them using push pull.…So I'm gonna go ahead and push and pull these into objects.…And notice how one has hard edges,…the other one is completely smooth.…Now fundamentally, these are the same objects.…So if I were to select, say my cylinder,…and right click over this and do select All Connected,…you'll see that I have all of these hidden edges…that show up in a dotted line.…

Learn how to start drawing, designing, and animating your ideas with SketchUp, the 3D modeling toolkit used for everything from architectural rendering to game design. In this course, George Maestri leads viewers through the essentials of SketchUp: navigating around the interface, manipulating objects, drawing in 2D and 3D space, working with materials, and applying textures. He'll even show how to create simple animations and export your artwork in 2D and 3D formats.

These tutorials work with both SketchUp Make, the free version of the program, and SketchUp Pro.
